Your definition of 'no problems' must be significantly different from my definition. Try comparing a connection through LHR with a connection through say ZRH. Maybe your expectations have just been conditioned by having to use it UKtravelbear. I am far from alone in saying avoid LHR if at all possible.

I think a lot of people simply accept the stress of things like long line-ups etc. that exist in many airports. Put simply, they don't know any different. Have you ever gone through the Passport Control Hall at Zurich airport UKtravelbear?

Here is what it looks like most of the time:


At busier times, there may be a few people line-up.



Do you want to try comparing to LHR? This kind of difference holds throughout. The fact that LHR handles so many people per day IS the problem UKtravelbear and the reason to avoid it if possible. There are far better airports through which to enter or transit in Europe. Trying to say that pointing that out is 'scare mongering' is ridiculous. What's more, it is not going to improve after Brexit or are do you think it is?
